Based on TPU(Thermoplastic polyurethanes) airbags, the actuator is designed by the use of nested structure combined with rope mechanism, which achieves a large expansion ratio (115%) on the premise of ensuring the rest size of the actuator. Then, according to the structural characteristics of the actuator, the static driving characteristics of TPU airbag and rope mechanism of the actuator are deduced by analytical and geometric methods. So the static model of output force of the actuator is obtained. Finally, a modeling method of using displacement-driven variable load instead of rope mechanism to construct simulation model is proposed. This research lays the foundation for the follow-up study of the actuator's dynamic characteristics and control strategy.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"108 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113969411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the method of aerodynamic drag estimation for the ultra-low orbit spacecraft is given, and the influence factors of aerodynamic drag are analysed, the calculation formula of drag coefficient is emphatically derived, and the influence factors of drag coefficient are studied. The drag coefficients under the conditions of typical orbit and space environment are given. In order to reduce the drag, the SLO spacecraft should be designed as a slender body configuration, and at this time, the drag effect brought by the side cannot be ignored, which should be paid more attention to in the overall configuration and layout design of the spacecraft.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"338 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122439863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
